Abstract: A centrifuge device is provided for the sizing and separation of constituents of a biologic mixture, e.g., adipose tissue. The device provides for the mechanical breaking down of the fibrous structure in the tissue by centrifugation causing the tissue to pass through a mesh element, or a sizing helix, or an extrusion element, whereupon the material is reduced to a slurry. This processed material may then be separated by centrifugation into its constituents, in order to harvest the fraction containing the multipotent cells. These multipotent cells may be utilized for various medical procedures to stimulate healing and tissue regeneration.

Abstract: Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.

Abstract: A catheter may include electrodes for transvascular nerve stimulation. The electrodes may be positioned within lumens of the catheter and aligned with apertures in the outer wall of the catheter. The electrodes may produce focused electrical fields for stimulation of one or more nerves. In one embodiment, the catheter may include a set of proximal electrodes and a set of distal electrodes, and the proximal electrodes may stimulate a patient's left phrenic nerve and the distal electrodes may stimulate a patient's right phrenic nerve.

Abstract: A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal.

Abstract: This disclosure describes, among other embodiments, a catheter. The catheter may include an outer layer defining a plurality of apertures therethrough, and a body defining at least one longitudinal lumen therein. The body may be within the outer layer, and the apertures may be radially outward of the lumen.

A ribbon cable may extend through the lumen and include a plurality of leads, with the plurality of leads being electrically connected to the plurality of electrodes. The plurality of leads and electrodes may be formed by the deposition of conductive inks or paints, or by the electrodeposition of copper or other conductive metals or materials.
